摘要 logback.xml配置如何按天输出日志文件

<?xml version="1.0" encoding="UTF-8"?>

<configuration>

<appender name="stdout"

class="ch.qos.logback.core.ConsoleAppender">

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{HH:mm:ss} [%thread] %-5level %logger{80} - %msg%n

</Pattern>

</layout>

</appender>

<appender name="R"

class="ch.qos.logback.core.rolling.RollingFileAppender">

<File>../ptvslog/server.log</File>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{HH:mm:ss} [%thread] %-5level %logger{80} - %msg%n

</Pattern>

</layout>

<rollingPolicy

class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">

<maxIndex>2</maxIndex>

<FileNamePattern>../ptvslog/server.log.%i</FileNamePattern>

<MaxFileSize>50MB</MaxFileSize>

</triggeringPolicy>

（1）第一种配置如下时，将会使日志文件往后累加，而不是每日只生成当日的日志文件

<appender name="logfile"

class="ch.qos.logback.core.rolling.RollingFileAppender">

<File>../ptvslog/access.log</File>

<rollingPolicy

class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>

../ptvslog/access.%d{yyyy-MM-dd}.log

</FileNamePattern>

<!-- keep 1 days worth of history -->

<MaxHistory>1</MaxHistory>

</rollingPolicy>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{yyyy-MM-dd HH:mm:ss} -%msg%n

</Pattern>

</layout>

</appender>

（2）第二种配置如下时，按天生成日志文件，每天的日志文件里只保存当天的日志信息

<appender name="logfile2"

class="ch.qos.logback.core.rolling.RollingFileAppender">

<Prudent>true</Prudent>

<rollingPolicy

class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>

../ptvslog/access.%d{yyyy-MM-dd}.log

</FileNamePattern>

<!-- keep 60 days worth of history -->

<MaxHistory>60</MaxHistory>

</rollingPolicy>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{yyyy-MM-dd HH:mm:ss} -%msg%n

</Pattern>

</layout>

</appender>

（2）第三种配置如下时，按天生成文件夹，每个文件夹里放当天的日志文件

<appender name="logDirfile"

class="ch.qos.logback.core.rolling.RollingFileAppender">

<Prudent>true</Prudent>

<rollingPolicy

class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>

../ptvslog/%d{yyyy-MM-dd}/access.%d{yyyy-MM-dd}.log

</FileNamePattern>

</rollingPolicy>

<layout class="ch.qos.logback.classic.PatternLayout">

<Pattern>

%d{yyyy-MM-dd HH:mm:ss} -%msg%n

</Pattern>

</layout>

</appender>

以下配置表示DataController类的INFO日志以logDirfile输出，additivity="false"表示只在

logDirfile输出，不在其他输出台输出，如果设置为true，表示要在其他地方也输出。

<logger name="com.apabi.ptvs.web.DataController"

additivity="false">

<level value="INFO" />

<appender-ref ref="logDirfile" />

</logger>

<root level="INFO">

<appender-ref ref="stdout" />

<appender-ref ref="R" />

</root>

</configuration>
